House Minority Leader Nancy Pelosi on Tuesday launched political grenades at Mitt Romney, arguing that Republicans haven’t coalesced behind the GOP frontrunner because they don’t believe he can beat President Barack Obama in November.

The House’s top Democrat repeatedly jabbed at the former Massachusetts governor during an hour-long interview hosted by POLITICO and taunted the GOP for a slate of presidential contenders that she said was “not exactly what you would call the first string of the Republican Party.”

“If the far right thought that Romney could win, they might be more enthusiastic about him,” Pelosi told POLITICO’s Mike Allen during Tuesday’s Playbook Breakfast. “But they question what he stands for and they don’t think he’s going to win. So what’s the sell? I’m not sure he knows what he stands for, and that makes it harder too.”
